They may be tiny weapons, but Brigham Young University's holography research group has figured out how to create lightsabers -- green for Yoda and red for Darth Vader, naturally -- with actual luminous beams rising from them.

Inspired by the displays of science fiction, the researchers have also engineered battles between equally small versions of the Starship Enterprise and a Klingon Battle Cruiser that incorporate photon torpedoes launching and striking the enemy vessel that you can see with the naked eye.

Today, deliveries via cesarean sections, or c-sections, have become quite common globally. Sometimes, c-sections are a medical necessity when normal deliveries become risky either for the mother or the baby. At other times, it can be a choice. C-sections today have become a considerably safer procedure than it was a few decades ago, but there is need to refine it further.

Children ages two to five who have the most common form of cystic fibrosis (CF), caused by two copies of the F508 gene mutation, have not had any modulator treatments available to them until recently.

Nanofabrication of electronic devices has reached a single nanometer scale (10-9 m). The rapid advancement of nanoscience and nanotechnology now requires atomic-scale optical spectroscopy in order to characterize atomistic structures that will affect the properties and functions of the electronic devices.

Recently, Prof. XIE Can from the High Magnetic Field Laboratory of the Hefei Institutes of Physical Science (HFIPS), in a collaboration with Prof. YAN Xiyun's lab from the Institute of Biophysics, reported the structural basis of mAb AA98's inhibition on CD146-mediated endothelial cells (EC) activation and designed higher affinity monoclonal antibody HA98 for cancer treatment.

Australia, the driest inhabited continent, is prone to natural disasters and wild swings in weather conditions - from floods to droughts, heatwaves and bushfires.

Now two new Flinders University studies of long-term hydro-climatic patterns provide fresh insights into the causes of the island continent's strong climate variability which affect extreme wet or dry weather and other conditions vital to water supply, agriculture, the environment and the nation's future.

Ishikawa, Japan - As decarbonization progresses rapidly in the world, fuel cells offer potentially higher electrical efficiency than conventional power-generating systems. Anion exchange membrane fuel cells offer advantages of using non-precious metal catalysts than proton exchange membrane fuel cells. One of the challenges of this next-generation fuel cell is to clarify the hydroxide ion conductivity in the ion conductive polymer around the electrode catalyst.

RNA-based drugs have the potential to change the standard of care for many diseases, making personalized medicine a reality. This rapidly expanding class of therapeutics are cost-effective, fairly easy to manufacture, and able to go where no drug has gone before, reaching previously undruggable pathways.

Mostly.

So far, these promising drugs haven't been very useful in getting through to the well-protected brain to treat tumors or other maladies.

If you are reading this, chances are you have several other tabs open in your browser that you mean to get to eventually.

Internet browser tabs are a major source of friction on the internet. People love them. People hate them. For some users, tabs bring order and efficiency to their web browsing. For others, they spiral out of control, shrinking at the top of the screen as their numbers expand.

A comprehensive review into what we know about COVID-19 and the way it functions suggests the virus has a unique infectious profile, which explains why it can be so hard to treat and why some people experience so-called "long-COVID", struggling with significant health issues months after infection.

Training the artificial intelligence models that underpin web search engines, power smart assistants and enable driverless cars, consumes megawatts of energy and generates worrying carbon dioxide emissions. But new ways of training these models are proven to be greener.

A new experiment shows that the more energy consumed by a clock, the more accurate its timekeeping.

A research team from the Skoltech Center for Design, Manufacturing and Materials (CDMM) studied the effects of processing additives - aluminum hydroxide and zinc stearate - on the polymerization kinetics of thermosets used in pultrusion. The research was published in the Journal of Composite Materials.

The Korea Institute of Civil Engineering and Building Technology (KICT) has announced the development of a fully-automated peak-picking method for cable monitoring. The developed method will improve reliability of the method. Such as Incheon Bridge in South Korea, Cable-stayed bridges have received significant attention as efficient structural systems worldwide. In this regard, newly developed cable monitoring systems have become an essential and efficient maintenance approach for cable-stayed bridges.

Social factors such as education, financial stability, food security and the neighborhood where someone resides were strongly correlated with whether or not individuals with heart disease adopted measures to prevent the spread of COVID-19, including wearing masks and working from home, according to a study presented at the American College of Cardiology's 70th Annual Scientific Session. The researchers say the findings draw attention to longstanding challenges related to social determinants of health.
